Binary datatypeedit

The binary type accepts a binary value as a Base64 encoded string. The field is not stored by default and is not searchable:

PUT my_index
{
  "mappings": {
    "properties": {
      "name": {
        "type": "text"
      },
      "blob": {
        "type": "binary"
      }
    }
  }
}

PUT my_index/_doc/1
{
  "name": "Some binary blob",
  "blob": "U29tZSBiaW5hcnkgYmxvYg==" 
}

The Base64 encoded binary value must not have embedded newlines \n.
